Have you ever asked yourself, why is my MacBook pro's battery draining so fast?  Why is my mac dying so fast? And how long does a MacBook battery last even? Because when you first bought your MacBook you could easily work on it for hours upon hours but now you need to make a run for your charger in just 3-4 hours? Well, you are not alone. A lot of Mac users face the same thing every day.

But don't worry, by taking some easy precautions and adhering to some proven best practices you can make sure that your MacBook stays healthy and lasts a long time.

Here is a brief guide to following if you think your MacBook's battery is draining fast.

Part 1: How Long do MacBook Batteries Last?

Before we dive into how we can stop our MacBook battery from dying on us so fast, we first have to know how long does a MacBook battery last? Well, like its answer is one of the most annoying answers to any question; It depends upon several factors like your usage, your charging practices, and even your environment. But on average we can expect 10 hours of battery life from all the last MacBook and MacBook Pro's out there.

These are the maximum battery lives of different MacBooks based on usage:

  • MacBook Air (2018, 2019): 12 hours of web browsing on WiFi and 13 hours of video streaming on Apple TV.
  • 13in MacBook Pro (2018, 2019): 10 hours of web browsing on WiFi and 10 hours of video streaming on Apple TV.
  • 15in MacBook Pro (2018, 2019): 10 hours of web browsing on WiFi and 10 hours of video streaming on Apple TV.
  • 16in MacBook Pro (2019): 11 hours of web browsing on WiFi and 11 hours of video streaming on Apple TV.

These numbers are the best-case scenario battery lives and by taking the right steps you can expect these battery times on your MacBook as well. It is important to note that MacBooks use Lithium-Ion batteries and do slowly start to deteriorate after going through a lot of charging cycles. This is out of your hand because that is just physics and chemistry doing their thing. So don't expect your MacBook Pro 2011's battery to be performing the same as a MacBook Pro 2020's battery.

Part 2: How to Check MacBook Battery Life?

So how do you check that how long does your MacBook battery last? That is a pretty simple affair.

Follow these simple steps:
  1. Find the battery-shaped icon in your menu bar. Check if it has a battery percentage showing next to it.
  2. If it doesn't have a battery percentage showing next to it, just click on the battery icon.
  3. Click on show percentage.
  4. You can now see the battery percentage right next to the battery icon.

Monitoring battery percentage is a great way to check how fast you are draining your MacBook's battery life. You can also check an estimated battery life based on your current usage.

You can do that by following these steps:
  1. Open Activity Monitor, you can do that by pressing space and command together and type in activity.
  2. Click on the energy button.
  3. On the bottom of the screen, you can see the estimated battery life for your MacBook.

It's always a great idea to keep a check on battery life so you can identify when and if your battery is draining too quickly.

Part 3: Why is My MacBook Dying so Fast?

Again, this can depend upon several factors. Usually, a MacBook dying very fast is an indicator that your MacBook is using a lot of energy.

Running an older version of the macOS can cause your battery to drain faster. Every update that Apple releases to the macOS is made to make your MacBook a better machine.

Older versions of the application are not optimized or efficient at using the available power. So, updating all your application whenever possible can go a long way to increase the battery times on your MacBook.

You can update your applications by following these steps:
  1. Launch the App Store.
  2. Click on 'Update' found at the top of the window.

Programs running in the background are a major source of your MacBook using up your precious battery life. Even though a lot of these programs are just running idle in the background, but they can be a major source of battery usage. It is always a good idea to cut down on background processes. By turning off all non-essential programs running in the background, you can almost double your battery life.

4MacBook Settings that Use More Battery

You can check and set the following settings to make sure you are not losing battery life unnecessarily:

  • Bluetooth turned ON: Bluetooth can take a major chunk of your battery when it is turned ON. Even when no device is connected to it.
  • WiFi turned ON: Similar to Bluetooth if WiFi is on and you are not connected to any internet device it will still drain your battery.
  • Lower Brightness: This one is a no-brainer, the higher your brightness, the more power your MacBook consumes.
  • Keyboard Backlighting:Even though it isn't as major as the other factors, keyboard lighting can still pull a significant chunk of power. Turning it down or even off will help.
